If you're reading this, chances are that you've heard of intraday trading. But what is it? Intraday trading is a type of day trading strategy in which traders buy and sell stocks during the course of one day only. This means that if you have an intraday trade open at 3 p.m., then when the markets close at 4:30 p.m., your position will be closed automatically with any profits or losses tallied up for that day only - no matter how long ago you opened it! Needless to say, there's a lot more risk involved in this kind of trading since new trades can get opened and closed multiple times on any given day; but for those who know what they're doing and follow their strategy religiously, intraday trading can be an extremely profitable endeavor.
